Waldhausen's Nil Groups and Continuously Controlled K-theory, by Hans J. Munkholm and Stratos Prassidis

In this paper we establish a connection between the Nil groups that occur in Waldhausen's description of the K-theory of a pushout of two groups over a common subgroup (or an HNN extension of groups) and the continuosly controlled K-theory groups defined by Anderson and Munkholm (in number 23 of these K-theory archives).
